AN INVESTIGATION INTO OPTIMAL GUIDANCE LAW OF SURFACE-TO-AIR MISSILE

Setting up a mathematical model of a missile and target state system in condition of no simplification of missile' s motion, the paper obtains a optimal guidance law by which the missile can attack a maneuvering target. The law is expressed in parameters measured by a radar. The law was applied to some surface-to-air missile control systems to verify its performance. The numerical computation shows that the guidance accuracy is good and the law can be used in real missiles. The effect of the elevation angle and the asimath angle at the initial controlling point on missdistance is studied here. The results show that the guidance law can loose restriction on the launching condition for a missile.
